We report the multiplicity dependence of charged particle productions for π±, K±, p, p and ϕ meson at |y| < 1.0 in p+p collisions at √(\rm s) = 200 GeV with \rm PYTHIA simulation. The impact of parton multiple interactions and gluon contributions is studied and found to be possible sources of the particle yields splitting as a function of pT with respect to multiplicity. No obvious particle species dependence for the splitting is observed. The multiplicity dependence on ratios of K-/π-, K+/π+, p/π-, p/π+ and Λ/K0s in mid-rapidity in p+p collisions is found following the similar tendency as that in Au+Au collisions at √sNN = 200 GeV from RHIC, which heralds the similar underlying initial production mechanisms despite the differences in the initial colliding systems.
